In this study, performance of zero and three dimensional simulations codes that used for simulate a homogenous charge compression ignition (HCCI) engine fueled with Primary Reference Fuel PRF (85% iso-octane and 15% n-heptane) were Circle S Barrel Saddle investigated.0-D code, called as SRM Suite (Stochastic Reactor Model) which can simulate engine combustion by using stochastic reactor model technique were used.Ansys-Fluent which can simulate computational fluid dynamics (CFD) was used for 3-D engine combustion simulations.Simulations were evaluated for both commercial codes in terms of combustion, heat transfer and emissions in a HCCI engine.
Chemical kinetic mechanisms which developed by Tsurushima including 33 Shark Cartilage species and 38 reactions for surrogate PRF fuel were used for combustion simulations.Analysis showed that both codes have advantages over each other.
